Hello! It's been a bit since I dug into hyper, but that's surprisingly low. Just to check, did you compile this with optimizations enabled, like `cargo build --release`?
[package]
name = "hammer"
version = "0.1.0"
authors = ["me"]
[dependencies]
hyper = "0.10"
[profile.release]
opt-level = 3
debug = false
rpath = false
lto = false
debug-assertions = false
codegen-units = 1
panic = 'unwind'
